These components demonstrate how investment casting can integrate curved blade profiles, mounting features, reinforcing ribs and complex structural details into near-net-shape steel parts. Combined with CNC machining and inspection, this approach supports reliable assembly, stable mechanical performance and consistent dimensional accuracy.

Casting and Machining Features for Instrumentation Components

Power equipment and industrial instruments often require compact components with several functional features integrated into a single part. Investment casting helps reduce welded or assembled structures while CNC machining provides accuracy at critical interfaces.

Complex Compact Geometries

Produce compact components with curved profiles, mounting arms, ribs and integrated structural details.

Internal Cavities and Passages

Form internal cavities, channels and functional openings that may be difficult to manufacture entirely from solid material.

Threaded Ports and Connections

Machine internal and external threads for sensors, instruments, probes and mechanical interfaces.

Precision Bores and Mounting Holes

Control bore diameter, hole position and mounting alignment through secondary CNC machining.

Machined Sealing and Contact Surfaces

Finish sealing faces, mounting surfaces and assembly interfaces according to drawing requirements.

Integrated Mounting Features

Combine brackets, bosses, flanges and positioning structures into one casting to reduce welding and assembly operations.

From Drawing to Finished Instrumentation Components

Each project is evaluated according to component geometry, material, operating conditions, machining requirements and inspection criteria before production begins.

Investment casting and machining production process for power and instrumentation steel components

Step 1：Drawing and Requirement Review

Review dimensions, material grades, tolerances, machining areas and functional interfaces.

Step 2：Casting Design and Tooling

Evaluate wall thickness, fillets, draft considerations, shrinkage allowances and machining stock.

Step 3：Wax Pattern and Ceramic Shell

Produce wax patterns and build ceramic shells through controlled dipping and drying processes.

Step 4：Melting, Pouring and Cleaning

Cast the selected steel grade, remove the ceramic shell and complete cutting, grinding and initial inspection.

Step 5：Heat Treatment and CNC Machining

Perform heat treatment where required, followed by machining of threads, bores, holes, sealing faces and mounting surfaces.

Step 6：Inspection and Final Finishing

Verify material and dimensions before completing the specified surface treatment, marking and packaging.

Steel Materials for Power and Instrumentation Parts

Material selection depends on mechanical loads, corrosion exposure, operating temperature, wear conditions and the required surface finish. Zeren manufactures customized components using a range of steel materials based on customer drawings and technical specifications.

Stainless Steel

Suitable for sensor housings, instrument connectors and components requiring corrosion resistance and a clean surface.

Carbon Steel

A practical option for structural brackets, mounting components and general mechanical parts.

Alloy Steel

Used for actuator components, control mechanisms and parts requiring enhanced strength or heat-treatment performance.

Duplex Stainless Steel

Suitable for components exposed to aggressive industrial, marine or chemical operating environments.

Heat-Resistant Steel

Used for components operating near heat sources or under elevated-temperature conditions.

Wear-Resistant Steel

Suitable for selected mechanical control or contact components exposed to repeated friction and wear.
Final material grades are confirmed according to customer drawings, mechanical requirements, service conditions and applicable material standards.

Inspection for Critical Dimensions and Interfaces

Power and instrumentation components may include closely positioned holes, threaded ports, sealing faces and assembly interfaces. Inspection is therefore focused on material verification, dimensional consistency and the accuracy of critical machined features.

Material Verification

Chemical composition can be verified using spectrometer testing according to the specified steel grade.

Dimensional Inspection

CMM, gauges and conventional measuring equipment are used to inspect critical dimensions and geometric relationships.

3D Scanning

Complex profiles and cast geometries can be compared with the original CAD model where required.

Hardness Testing

Heat-treated components can be checked to confirm that specified hardness requirements have been achieved.

Thread and Bore Inspection

Threaded connections, precision bores and mounting holes are checked using suitable gauges and measuring tools.

Surface and Visual Inspection

Cast surfaces, machined interfaces and finished components are visually inspected before shipment.
